E-16: Standard for Compressed Gas Check Valves for Pressures up to 3000 psi
This standard applies to check valves used in general industrial and medical compressed gas service designed for service pressures up to 3500 psi (24 130 kPa) at 120° F (49° C), and used in conjunction with cylinder valve or manifold connections specified by various standards of CGA. These connections may be incorporated as part of equipment; such as: regulator inlet connections, manifold connections, or other high pressure hose line (pigtail) inlet and outlet connections.

This standard does not apply to check valves used as an integral part of a regulator, residual pressure cylinder valve, gas pump, or otherwise internal component of other equipment. This standard does not apply to cryogenic or liquefied gas check valves.
